  • Page 4: Delfi Portable Tourniquet System (P.t.s.) General Information

    INTENDED USE The Delfi Portable Tourniquet System (P.T.S.) is intended to be used by qualified medical professionals to temporarily occlude blood flow in a patient's extremity during surgical procedures on that extremity. Tourniquets are generally used for operations lasting less than 90 minutes. Tourniquets have been found...

  • Page 5: Adverse Effects

    • Prolonged tourniquet time can also produce changes in the coagulability of the blood with increased clotting time. Always minimize tourniquet time. • Tourniquet paralysis may result from excessive pressure. Insufficient pressure may result in passive congestion of the limb with possible irreversible functional loss. Always use the minimum effective tourniquet pressure, as described in the medical literature.

    We recommend that this inspection be performed by a qualified biomedical engineer or other person thoroughly familiar with electronic medical devices. If the unit is damaged, notify the carrier and Delfi immediately. If the initial inspection results are satisfactory, a functional and calibration check should be performed after an 8-hour charge.
